The use of genome-wide association studies in medical research and the increased ability to share data give a new twist to some of the perennial ethical issues associated with genomic research. GWAS create particular challenges because they produce fine, detailed, genotype information at high resolution, and the results of more focused studies can potentially be used to determine genetic variation for a wide range of conditions and traits. The information from a GWA scan is derived from DNA that is a (...) powerful personal identifier, and can provide information not just on the individual, but also on the individual's relatives, related groups, and populations. Furthermore, it creates large amounts of individual-specific digital information that is easy to share across international borders. This paper provides an overview of some of the key ethical issues around GWAS: consent, feedback of results, privacy, and the governance of research. Many of the questions that lie ahead of us in terms of the next generation sequencing methods will have been foreshadowed by GWAS and the debates around ethical and policy issues that these have created.

In Phillip Kerr’s 1994 spellbinding novel A Philosophical Investigation, the medical test to which the protagonist refers is a functional brain scan based on positron emission tomography. It is used to run large studies of male and female brains and, following a lead suggested by animal studies, has been used to identify rare cases of human male subjects who lack the ventral medial nucleus. This nucleus, in the experiment, is hypothesized to inhibit the activity of the sexually dimorphic nucleus, a (...) preoptic area of the male brain believed to be a repository of male aggressive response. Prior research, we learn from the plot, shows that 3 in 100,000 human males are VMN-negative. Thirty percent of those affected are believed to be in prison or to have a criminal record; 70% are believed to stabilize levels of aggression by producing increased levels of estrogen. Identities of subjects participating in the brain scan studies are protected through the conversion of real names to those of famous figures of the past — Bertrand Russell, Charles Dickens. Those for whom results are unfavorable are recontacted, and they are offered counseling. (shrink)
